Question

If the principle is doubled in six years find the rate of interest

Answer 1

Answer:

Step-by-step explanation: take p as 2p

          t= 6

          r= ??

           but lets just take p as 100  which will be for 3 years

            take A = 150

          then SI will be 50

            then in 6 years it will be 200 then si will change to 100 then A will be 300

so now rate = 100x100/200x6 = 8.3333% and yes this is your answer
